DEVICE FOR REMOVING SCALE FROM SHEET METAL.

SPECIFICATION forming part of Letters Patent No. 688,450, dated December 10,1901;v

Application filed April 29, 1899. Renewed June 29, 1901. Serial No. 66,528. tNo model.)

hereby declare the following to be a full,clear,-

and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in a device for removing scale from sheet metal.

The invention has for its object the provision of a means of removing the scalefrom sheet metal during the process of rolling the same into marketable material. p

The device consists in applying a pair of heavy wire brushes to the housings at the rear of the rolls, sothat the sheet of metal in issuing from the rolls may pass between them and remove said scale from both sides of the sheet.

, The deviceis not alone practical, butis comparatively simple in structure and inexpensive to manufacture.

Other improvements are combined with the housings and rolls to prevent the lubricating material upon the bearings from working onto the surfaces of the rolls.

With these objects in view the invention finally consists in the novel construction,combination, and arrangements of parts, as will be hereinafter more fully described in detail.

In describing the same in detail reference is had to the accompanying drawings, wherein like numerals of reference designate like parts, and in which I Figure 1 is a plan view of a pair of rolls and housings having my improvements thereon. Fig. 2 is a rear elevation of the same. Fig. 3 is a sectional side elevation through the rolls and brushes on the line A B of Fig. 2. Fig. 4 is a perspective view of the top brush. Fig. 5 is av perspective view of the lower brush. Fig. 6 is a face view of one of the roll-pro tectingplates. Fig. 7 is an end View of a pair of rolls with brushes of rotary form, being a modification.

In the drawings the numeral 1 designates a pair of housings arranged upon a bed-plate 2, said housings having in connection therewith a pair of plain-faced sheetor plate rolls 4 and 5. These parts beingold in the art of iron and steel manufacture are not of my invention and may therefore be of any approved form.

To remove the scale which forms upon the surface of the plate during the process of manufacture and at the time when the plate issues from the rolls, I arrange a brush formed of a metal bar 6, having a number of steel wires 6, attached at its under side to the housings. Said brush-bar has'shouldered ends, which engage within a pair of U-shaped brackets 7, arranged upon the inner sides of the housings at the rear of the rolls, said brush being capable of moving upward to adjust itself when the plate passes beneath it. The lower brush-bar 8 is also constructed of metal and is provided with wires 8 upon its upper side. i This brush issuspended upon a bar 9, reaching across between the housings, by the hook-shaped lugs or hangers 10, which are formed upon the brush-bar. Slightly elevated above the meetingpoint of the rolls and brushes is placed the roller 11, whose ends are reduced in diameter to form bearings and are fitted into brackets 12 upon the housings. The bar 9 is provided with a pair of guide arms 12, which extend upward to the roller and serve to guide the metal sheet up over the roller after passing through the rolls and brushes.

To prevent the lubricating material from working onto the surface of the rolls, I attach by set screws or bolts 13 to the inner sides of the housings a plate formed of the two sections 14 and let, having openings 15 and 15 to engage over the reduced necks of the rolls. These openings and those 16 for the bolts are made elongate or elliptic in. form, the object of which is that the rolls may be adjusted.

At Fig. 7 a variation is shown by placing with the rolls 4 and 5 a pair of rotary brushes 20 and 21.

Having thus fully shown and described my invention, what .I claim as new, and desire to secure by Letters Patent, is

1. The combination with a pair of rolls and their housings, of a pair of brushes extending between the housings at the rear of and parallel with the rolls, a bar 9 fitted within openings at the inner sides of the housings and provided with arms 12', the roller 11 supported by brackets upon the rear of the housings and parallel with the rolls, the plates 14 and 14 having elongated openings 16 whereby they are adjustably attached to the inner sides of the housings, and the elongated openings 15 and 15, to engage over the reduced portions of the roll-necks, as shown and set forth.

2. The combination with a pair of rolls and their housings, of the brackets 7, the brush 6 supported within the said brackets, the bar 0 having the arms thereon, the openings in the housings to support said bar, the brush 8 and set forth.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing Witnesses.

JAMES '1. WAGNER.
